Air moves in and out of a home through every hole, crack, and crevice. Roughly 33% of air infiltrates through walls, ceiling, and floors. Adding an advanced insulation system is necessary to achieve optimal building performance. Lapolla is that advanced insulation system.
Spray foam insulation can maximise a homeowner’s investment by sealing the building envelope to stop conditioned indoor air from escaping and prevent unconditioned air from entering a home. Air exchange in and out of a home is a leading cause of escalated energy bills. The mechanical systems that heat and cool buildings are continuously operating; reducing extreme temperature variations saves on the overuse of mechanical systems and leads to lower energy bills.
LIMITS OF R VALUE
R value measures insulation’s ability to limit conductive heat flow (heat that is transferred through it). But the primary method of heat transfer is not conductive heat flow — it’s air leakage, which can account for up to 40% of a property’s energy loss.
In addition, R value only does so much to prevent even conductive heat flow. Beyond a certain point, improving insulation R value makes very little difference, if any. Above a certain thickness of insulation material the heat flow reduction due to conduction reaches a plateau. In fact, the cost of improving R value alone can actually far outweigh the energy savings that result, meaning it will take much longer to break even.
Therefore, the best way to increase efficiency is not merely to improve R value, but rather to combine R value with an air barrier. Lapolla AirTight spray foam insulation provides both in a single step.
